DARWIN'S MACROEVOLUTION: Why Unscientific?

[genkaus]

ALTER2EGO -to- EVERYONE:

DEFINITION OF MICRO-EVOLUTION:
"Evolutionary change below the species level; change in the genetic makeup of a population from generation to generation." (SOURCE: Biology, 7th ed. Neil A. Campbell & Jane B. Reece)


DEFINITION OF MACRO-EVOLUTION:
"Evolutionary changes that happen over very long periods of time. This usually refers to the development of large new branches of life, such as vertebrates or mammals." (SOURCE: Evolution: The History of Life on Earth, Russ Hodge)


DEFINITION OF SPECIES:
Loosely speaking, a species is a related group of organisms that share a more or less distinctive form and are capable of interbreeding. As defined by Ernst Mayr, species are:

"groups of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups."

Fine.

ORGANIC/BIOLOGICAL EVOLUTION is the theory that the first living organism as it reproduced, it is said to have changed into different kinds of living things, producing ultimately all the different forms of life that have ever existed on earth, including humans. (Sources: (1) LIFE--How Did It Get Here? By Evolution or by Creation? pages10-11; (2) Encyclopedia Britannica, page 1018)

Fixed that for ya.

DARWIN'S THEORY IN 1859:
"Therefore I should infer from analogy that probably all the organic beings which have ever lived on this earth have descended from some one primordial form, into which life was first breathed." (Origin of Species, p. 484)

Good thing we have come a log way since 1859.

EVOLUTION THEORY IN 2012:
"The commonly accepted scientific theory about how life has changed since it originated has three major aspects.

"1. The common descent of all organisms from (more or less) a single ancestor.

"2. The origin of novel traits in a lineage

"3. The mechanisms that cause some traits to persist while others perish"

Looks fine.

DISCUSSION QUESTIONS:
1. Just like Charles Darwin, the modern-day evolution scientific community asserts that every single animal that has ever existed came from one common ancestor aka came from a single animal (macro-evolution). Is there evidence proving that humans or animals evolved from completely different beings than what they presently are?

Ofcourse not. Why would you expect them to have evolved from completely different beings? Read the data you yourself provided - "The mechanisms that cause some traits to persist". This clearly means that organisms would always bear some similarity to their ancestors and would never be completely different beings. Our ancestors were Eukaryotic organisms and we are still Eukaryotic organisms.

2. Fossils are the bones of long-dead animals. Do fossils exist that show evolutionary transition of one type of animal to an entirely different type of animal (eg. a whale evolving into a bear)--which is an example of macro-evolution?

Never. Since that is not macro-evolution, doesn't happen, isn't expected to happen and if it happened it'd blow the theory of evolution out of the scientific water.

3. When people in the pro-evolution scientific community speak about animals evolving into "new species," are they referring to one family of animal evolving into an entirely different family of animal (eg. a squirrel evolving into a bat or a dinosaur evolving into a bird)--which are examples of macro-evolution? Or are they referring to variations of the exact same type of animal (eg. Doberman dog, Bull dog, Rottweiler dog)--which is an example of micro-evolution?

Get your terms straight. Animals of one family never suddenly evolve into another family. And "type of organism" is not a scientific classification. Reform the question and it'll be answered when and if it makes sense.
